F12, the below excerpt from the 10K answers your question about sampling and who is doing the fulfillment. It can be found on page 2 under Non-Digital Products and Services. Truthfully, it has not been crystal clear to me, but with this paragraph it is now.

"...on February 28, 2020, we executed a letter of intent with Range Printing, a company in the business of providing enterprise class printing, sample assembly, warehousing, packaging, shipping and fulfillment services. Pursuant to the letter of intent, through an automated process we have established for this purpose, Range will receive orders for samples and merchandise from us as and when we receive them from our clients and users, and print, assemble, store, package and ship such samples and merchandise on our behalf. The Range letter of intent provides for a revenue share arrangement based upon the specific services to be provided by Range that is designed to guarantee net revenue to us, maintain our relationship with our clients by continuing to service their non-digital needs, while eliminating the labor and overhead costs associated with the provision of such services by us."
